1 Claim.

My invention relates to a method of rebuilding worn rubber heels. It is well known that rubber heels of shoes are usually worn down at the rear outer portion of the heel. An object therefore of this invention is to provide a method by means of which the worn lower surface of the heel may be readily rebuilt. Another object is to provide for rebuilding the heel in such manner that the resiliency of the heel will not be impaired. In carrying out my method, I provide sheet rubber, cut therefrom a crescent shaped piece of suitable size, and cement this piece to the worn place in such manner that the heel will be rebuilt.

The novel features which I believe to be characteristic of my invention are set forth with particularity in the appended claim. The invention itself, however, both as to organization and method of use, together with additional objects and advantages thereof, will be best understood from the following description of a specific em bodiment when read in connection with the accompanying drawings in which Fig. 1 is a bottom plan view of the rebuilt heel.

Fig. 2 is a side elevational View thereof.

Fig. 3 represents sheet rubber on which a piece of the desired shape and size has been outlined for cutting.

Fig. 4 is a bottom plan view of a slight modification.

Fig. 5 is a side elevational view thereof.

Referring first to Figs. 1, 2 and 3, I provide a sheet rubber strip l3, cut therefrom a crescent shaped piece l0 of the proper size and shape for applying to the worn place of the rubber heel ll of a shoe I 2, and cement said piece to the worn place in such manner that the heel will be rebuilt.

While a rubber strip I3 may be provided of the proper thickness to correspond to the worn outer portion of the heel, I prefer to provide rubber patch material. In case the rubber heel has been worn down to such an extent that this material is not sufliciently thick, I proceed as follows as illustrated in Figs. 4 and 5. In these two figures, l I designates the rubber heel of a shoe l2. A crescent shaped piece 14 of a size to partly rebuild the worn heel is cut from the sheet material, and another larger crescent shaped piece 10' is cut therefrom. The piece H3 is first cemented to the worn place and then the larger piece I 0' is cemented thereover.

The operation and advantages of my invention will be apparent in connection with the foregoing description and the accompanying drawings. Since the rubber piece may be firmly secured to the rubber heel with cement, it is not necessary to use any nails or other metal parts. Therefore the resiliency of the heel is not impaired and furthermore there is no metal to provide a slippery surface on the bottom of the heel.

I claim:

The method of rebuilding worn rubber heels which consists in forming at the worn place in the heel a cavity with an ofiset edge, providing sheet rubber material, cutting therefrom a crescent shaped piece to fit the smaller cavity, cutting from the same material a larger crescent shaped piece to fit the larger cavity, cementing the smaller piece to the bottom of the cavity, and cementing the larger piece over the smaller piece to restore the tread face of the heel.
